I would argue that the IAL papers are the harder past papers, not the UK ones, and I personally think this paper was harder than any of the UK papers. Boundaries will be slightly lower than last year, I would've thought.

100 UMS: 70/75
90 UMS: 63/75

Now for the important boundaries:
80 UMS: 57/75
70 UMS: 51/75
60 UMS: 46/75
50 UMS: 40/75
40 UMS: 35/75

Where on earth are you getting this from? Is it just your predictions based on like 20 TSR members discussing an exam in a students' forum?

Grade boundaries:
100 UMS-75 maybe 74
A*-69-only because i got 69 lol.
A-59-it will not be any lower, no recent d1 paper was lower than 58.and there are harder past papers.
B-idk-i never get lower than this so i dunno.

There is no A* in D1. Only 90 UMS. Also the last two papers have been 70 and 71 for full. I know of very few people who finished in time, having done most of the questions correctly. It will not be 75 for full.

Of course. On the front of the question paper it states pencil is allowed for drawings and diagrams, provided it is dark

Did you have to simplify 20x + 65y =< 520?

Also I got C=2x+3y. Would this not be right because we aren't given a value for capacity, only relative capacity?

Fine and fine

Was there a question on dijkstras about finding a route via J ? Think I completely missed that question :frown:

how many marks Is it worth ?

2 I remember. Maybe 3 but no more than that so don't worry.

I got C=1.5x+y as the objective line and that works cos y was meant to have a capacity 50% bigger and if you plug in values, it works. make c=9 and you'll see

I got that as well but I think it is wrong but the way that's worded means that for every y there is 1.5x which is the wrong way round cos y had 50% more so it should be 1.5y

Hopefully I'm wrong in calling you wrong because I also got c=1.5x+y really hope that method marks still apply though for the rest even if that's wrong

Nobody knows what the boundaries are but it doesn't hurt to try and predict them. Based on the fact that this exam was much harder than last year's then I really can't see it being more than 57 for an A...
